Although we’re living in the twenty-first century, there are still many dangers in our workplaces. For certain industries, such as the construction, manufacturing and industrial industries, the risks ...

Machines have evolved to meet the demands of daily life and industrial use, with molecular-scale devices often exhibiting improved functionalities and mechanical movements. However, mastering the ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

The problem of RB dynamics has aroused the interest of scientists to deal with it, and it is regarded as one of the important problems that have been extensively researched, due to its wide range of ...

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...

A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

The two degrees of freedom in movement can be actuated independently or concurrently. The actuators can be run using a two-axis stepper-motor driver and chopper and/or microstepping drives. The Size ...
